3.Now describe what is different about the particles in each diagram and try to explain how those differences relate to how solids, liquids and gases feel to the touch.
Solids are hard and strong. Just like a desk when you bang your hard to it, it would hurt because it's hard and strong. A solid can hold its own shape unless something happened to it, like if you have a chocolate and you melt it. The particles of solids are attached to each other.
Liquids flows around and will fill any container. Just like when you swim, the water follows the shape of the pool. Liquids feel weak and wet for example when you swim, you can push the water and you can feel it's wet. The particles are not attached to each other like solid but they're not far apart.
Gases- the feeling you get when you touch the gas is nothing, you can't touch gas. But you can feel it, like wind. It can always fill a container with any size and shape. The particles are spread out floats around.
Can you trust your senses?
TASK ONE 1. Where does the most bending of the light occur in the eye? The most bending of the light occur in the eye is at the light-bending parts which are the cornea and the lens. 2. Describe how the lens works.
The lens works almost exactly like the lens of a camera. The lens is located right behind the pupil and it works by focusing lights into the back of the eyeball. It is clear and curvy, it can change its shape depending on what object are you looking at (focusing at). 3. Why do we squint when exposed to bright light? Because the photoreceptive are senstive to light. Although the rods are more sensitive to light than the cones. And the rods pruduced light when a single photon hits it. So it is very sensitive, that sometimes we need to squint because the pupil probably cannot get any smaller when there is too much light coming into our eye. 4. Which parts of the eye are involved in focusing?
The parts of eye that are involved in focusing are:
the cornea- helps to focus as light goes through
the pupil- helps to control how much light is needed to come in. when there is enough light, the pupil will be smaller but it will get bigger if we go to a dark place. it will get bigger because it is trying to get lights from anywhere.
the lens- focusing lights into the back of the eyeball
5. Discuss the implications of losing one eye. Losing an eye effects you alot. Two eyes are better than one because without another eye your hand and eye coordination would not be really easy and it would be hard to not see with the two perspectives because sometimes one is not so accurate.

TASK TWO Discuss: Visual impairment Do you know anyone who wears glasses or contacts? Why? How do glass or contacts help?
I wear glasses and sometimes contacts. They help to get a perfect vision for people that have different shapes of eyeball which is pretty much what I have (genetic), I also know people that wear glasses because they got in an accident, and also one that has a disease. Glasses and contacts help by spreading the light out or by bringing light in. Are there other solutions for people with visual impairments? Other solutions for people with visual impairments is a laser surgery. Use the resource from the last section to find out about visual impairments -describe two visual impairments
:-short sighted: when the light stops before it hits your retina
:-long sighted: when the light stops way past the retina. -describe some possible solutions. -Find a picture or video clip and use this to support your ideas on your student page.
TASK FOUR Rhinoceros- has eyes that can see way behind. They are like that because Rhinos has huge bodies and are slow. So they need their eyes to work like that so they can see the predators from way far behind them, so that they can run way before the predator can reach them. But this means the rhinos can't see objescts infront of them really well. But they also do have a good hearing, they swivel their ears to focus on a specific sound. Seahorse- their eyes can move independently. This helps them to spot their prey, predators, or enemies without having to move their body.
